HEINRICH BRUS'I, OF CASSEL, GERMANY.

PROJECTILE.

Specification of Letters Patent.

Patented July 26,1910.

Application filed September 25, 1909. Serial No. 519,615.

To all whom it may concern Be it known that I, HEINRICH BRUST, a subjectof the Emperor of Germany, resid .mg at Cassel, Germany, have inventedcer- 'ive have not so far been successful.

The present invention relates to a projectile which will meet therequirements in that it involves the advantages of both shrapnels andcommon shells. -The improved projectile is composed of a casing which isfitted on the outside with fin-like worms, adapted to rotate theprojectile, during flight, round its longitudinal axis, and

which is provided in its lower portion with a shrapnel charge and in itsupper portion with a set of filllng projectiles charged with a powerfulexplosive. o

In the accompanying drawings the invention is illustrated, Fi ure 1representing a central section through the charged projectile, Fig. 2, acentral section through the empty casing, Fig. 3, a section of one ofthe filling projectiles, Fig. 4, a side view of the projectile showingits exterior worms, Fig.

5, a section of a filling projectile of another form of construction, 6,a sectional elevation of a projectile, showing a different way ofloading the same, and Fig. 7, a section along line AB of Fig. 6.

A casing 01', with cylindrical bore, has a bottom chamber 6- adapted toreceive the bursting charge for the shrapnel. The driving plate 0, whichis slightly arched, rests 'on a shoulder formed in the jacket and has acentral aperture for the reception of the ignition tube. The latter isdivided. into two parts d and e which arese-parated by a pellet f ofsome slowly burning powder. The sharpnel charge 9 rests on the drivingplate 0 and is covered by a disk h which is held by another shoulder inthe jacket a. Above the disk It a propelling-charge is provided, theobject of which is to d} We Oht,

by means of a driving plate is, the filling projectiles Z arranged onthe latter. The projectile is closed by a suitable'fuse capsule m whichis held in the casing a by a weak screw-thread allowing it to-disappearfrom the casing immediately the ignition takes place, so as to leave,the passage clear for the filling projectiles. v

To facilitate the loading of the casing,'it is preferably composed oftwo' parts screwed together, as shown in Fig. 2.

The casing a is fitted on t in any the air he outside Withfin-like wormsn, fixed to the casin sultable manner. The resistance 0 on said worms,during the flight of the projectile, effects a rotation of the latterround its longitudinal axis.

l/Vhen the projectile is loaded in the gun, the spaces between the wormsare filled with some fusible material, such as sulphur, resin, or thelike, so asto give the projectile a firm bearing in the gun.

The elongated filling projectiles -Z consist of a shell provided on thenose with a percussion fuse 0 and at the base with a fuse"p. Theinterior 9 ofv the shell is filled with an explosive of the mostpowerful nature, capable, when ignited by the percussion fuse o throughthe projectile striking. against any hard object, for instance aprotective armor,

of breaking such object into fragments. If not previously hitting any.object, the pro j ectile will, after a lapse of 2/ 10 second from thetime ofignition of the charge 71, 2'. 6., at a speed of 250 meters,after'a flight of. another 50 meters, be exploded by means of the fuse pwhich is ignited through the heat developed by the ignition of thecharge The'fiash which ignites the charge 71 also ignites the. pellet fwhich, after a lapse of 1/10 second, transmits the flash to the bottomchamber 6 which then effects a shattering of the shrapnel charge g.Through this interval-between the explosions of the different charges,the pro ectiles l will have time to make way for the bullets of; the.shrapnel charge. The advantage of the 1m-, proved projectile is,therefore, that it is capable, first of shatterin the protections of abattery and then of charge against the occupants. v V

The chance of hitting the battery is increased by the number of fillingprojectiles employed. p

When the elongated filhng projectiles can not be made to actsatisfactorily, the may irecting' the bullet be substituted byspherical-,proj ecti es, as

s an through the projectile striking against a hard object, for.instance an armor.

Figs. '6 and 7 show a different mode of loading the projectile. Theelongated filling projectiles are here arranged in metal tubes 1), outof which they are thrown by the propelling charges 2'. These tubes serveto direct the projectiles Z and revent them from turning over-during theight.

1. A"projectile,-comprising in combination, a casing fitted on theoutside with finlike'worms adapted to rotate the'projectile during itsflight, an ignition tube in the center of said casing, a shrapnelchargein the lower'portion of said jacket, a set of filling projectiles in theupper portion thereof, a propelling charge for driving out said fillingprojectiles, and a pellet of slowly burning powder in said ignition tubeadapt-. ed to delay theignition of the shrapnel charge till the fillingprojectiles have been driven out, substantially as and for the purposeset forth.

2. A projectile, comprising in combination, a casing fitted on theoutside with finlike worms, a fusible material provided in the spacesbetween said worms, a bottom chamber adapted to receive a burstincharge, a driving plate arranged over said chamber and resting on ashoulder in the casing, an ignition tube projecting through the centerof said plate, shrapnel bullets arranged round the lower part of saidtube,
